Blow up of solutions with positive energy in nonlinear thermoelasticity with second sound. (English) Zbl 1082.35101

The authors consider a nonlinear multidimensional thermoelastic systems where the heat flux is given by Cattaneo’s law with a source term. The existence of local solutions and blow up of global solutions, when the initial energy is sufficiently large, are proved.
